Show HN: Fermi Chain. A Wordle-style game for order-of-magnitude thinking

1 andrewrn 0 4/30/2025, 12:56:40 PM fermichain.com ↗
A couple weeks ago I posted a Fermi estimation game (https://news.ycombinator.com/item?id=43632278) I made it the hope that it would eventually help me become a lot more inclined to make these estimates during everyday life.

Just shipped a v2. It's more open-ended, closer to the spirit of true Fermi estimation, and a lot more mobile friendly. Would love any/all feedback!
